Background: To study the accuracy of one-stage and two-stage impression techniques. Materials & Methods: A synthetic model of a molar tooth was crafted in a resin laboratory using a standard procedure for creating complete dental crowns. The impression process was conducted ten times using both a one-stage technique and a two-stage technique, each time utilizing an appropriate tray. Statistical analysis was performed using an independent t-test, and the obtained data were processed using SPSS software. Results: In the case of the mesial region, the p-value was determined to be 0.01. The mean marginal gap resulting from the one-stage technique was found to be greater than that of the two-stage technique. Conclusion: There is higher accuracy for two-stage impression technique than for the one-stage impression technique.
